My choice would be to go to St Croix and I’d choose Cane bay Divers. There are great sites in both the BVI’s and at St Croix. If you want to stay at a resort style place you can’t go wrong with the Carambola resort and it’s righ up the road from Cane Bay. If you’d like to save a great deal of money and stay at a very nice condo. on the beach, take a look at Sugar Beach. Talk to Steve and see if you can get into unit #306.
If you decide on St. Croix I’d highly recommend taking both a night and day dive on "the Pier " it’s a great micro-dive.
